This story is meant to be long, but there is some improvements. They reveal certain information about the organization, but still manage to keep it vague. The final arc will probably be a confrontation between Shinichi and the organization. So unless the manga is ending soon, no way in hell that is happening. And the author still manages to keep the story interesting so you should give it a read still

I'd say it's 60% episodic, 30% character development, and 10% plot. The plot usually has hints here and there (like a suspicious recurring character is involved in a case), but the best thing is when the big plot arcs start. These arcs occur somewhat rarely, but when they do, they tend to last many chapters, with high tension and long-awaited revelations.

As for Conan being closer or not to getting his old body back...He's certainly closer than before, though it's mostly only apparent during the plot arcs. But it doesn't seem like he'll get his body back anytime too soon.

I agree to that and there are episodes or chapters that he turns back to shinichi then return to conan though...

Not really. I can't imagine there being anymore serious plot development until they actually focus on getting him back to being Shinichi. I mean, they've slowly acquired all the info they need now they just need to act on it. It's probably how they're going to end the series (the last arc) so they're just doing the usual until they feel like ending it, I guess.

But at the end of the day, I really like murder mysteries so it still manages to keep me entertained.
